Unfortunately I am having an issue with buffer_compress_chunk in the
2.2.12 release.  Removing buffer_compress_chunk from the tests below
fixes the issues.

fio --name=test --rw=write --bs=4k --ioengine=libaio --direct=1
--iodepth=32 --size=1g --refill_buffers
--buffer_compress_percentage=50 --buffer_compress_chunk=32k
--filename=testfile
test: (g=0): rw=write, bs=4K-4K/4K-4K/4K-4K, ioengine=libaio, iodepth=32
fio-2.2.12
Starting 1 process
fio: pid=24516, got signal=11


Run status group 0 (all jobs):

Disk stats (read/write):
  sda: ios=0/0, merge=0/0, ticks=0/0, in_queue=0, util=0.00%
fio: file hash not empty on exit


fio --name=test --rw=write --bs=128k --ioengine=libaio --direct=1
